INTRODUCTION

Safety Information

Cloud PM paging microphones operate from a low DC voltage, supplied by either an

AC adaptor or the Cloud host device to which the microphone is connected. As such,

the microphone requires few safety precautions.

However, note that both the metal base of the unit and the mic gooseneck will be

electrically connected to the chassis of the host device (e.g., Cloud zoner or mixer/

amplier) once the installation is carried out. This means that if the mains wiring of

the host device and/or the building is faulty, the microphone could present a shock

hazard. Fitting a suitable earth leakage circuit breaker (e.g., 30 mA RCD type) to the

mains supply of the host device can provide additional protection.

Overview

Thank you for purchasing this Cloud PM paging microphone.

Six models of the PM are available:

• The PM4, PM8, PM12 and PM16 are Digital Paging Microphones able to page to 4,

8, 12 or 16 zones respectively.

• The PM4-SA and PM8-SA are Digital Paging Microphones with built-in Message

Announcer capability. They can page, or send messages to 4 or 8 zones

respectively.

Physically, the PM4, PM8, PM12 and PM16 differ only in the number of zone select

buttons on the front panel, and consequently in the maximum of zones supported.

The PM4-SA is similar in operation to the PM4, but the front panel has an additional

4 buttons for the Message Announcer feature, and thus resembles the PM-8 in

appearance. Similarly, the PM8-SA has 8 more buttons than the PM8, and thus

resembles the PM16 in appearance.

PM models include the following basic features:

• Individual and multiple zone selection for both paging and messages (messages

apply to SA models only)

• External NC/NO message triggering (SA models only)

• Denable zone groups with group selection

• ‘TALK’ (‘TALK/SEND’ on SA model) and ‘CALL ALL’ buttons

• Pre-paging chime with internal chime sounder

• ‘BUSY’ LED

• Congurable two-layer paging priority system

• Auto zone reset after paging and zone disable

• Suitable for free-standing or wall mounted operation

The PM is designed to interface directly with several Cloud products - such as the

DCM-1, Z4/Z8MK4 and 46-120 - via the Cloud Digital Paging Interface, which uses

standard CAT-5 cable and RJ45 connectors. It is also provided with an

“analogue” interface, permitting it to be used with any other audio

system equipped with ‘short-to-ground’ paging access for selecting the

zone(s) to be paged. This includes the following current* Cloud products:

• CX163 Mixer

• CX263 Mixer

• 36-50 Integrated Mixer Amplier

*Other, older Cloud products may also be compatible; please contact Cloud’s Technical Department for

advice.

PM4/8/12/16 & PM4/8-SA Installation and User Guide v1.2

8

Multiple PMs may be interconnected (via the Digital Paging Interface) to permit

paging from more than one location. A total cable run of up 1 km is permissible, with

a maximum of 32 PM units. Different models of PM may be intermixed on a single

network. It is also possible to congure a PM to address only a subset of the available

zones.

The PM is also compatible with the older Cloud CDPM range of digital paging

microphones. PM microphones and CDPM microphones may be freely intermixed on

the Digital Paging Interface.

Scope of this manual

The bulk of this manual is intended to guide you through the installation and

conguration of the PM. Sections of the manual cover aspects such as power

requirements, connecting the unit to various types of host mixer, and conguring

the PM to suit the particular requirements of the installation. These sections will be

adequate for situations where there is only a single PM. A separate section covers

the various additional points that need to be considered when multiple PMs are

interconnected on a network.

The manual covers both standard PM microphones and the SA models, which include

a digital sound store for pre-recorded messages. The installation and operation of

the two models is similar in many respects; nevertheless there are some important

differences between the models. These include the additional wiring needed if the

stored messages are to be triggered externally, and the internal PCB layout and

jumper locations.

The sections of the manual which are specic to the PM4/8-SA are clearly indicated

by the use of a this icon

Wherever the term “PM” is used in this manual, the text can be taken to apply to all

models (both SA and non-SA) of the microphone. Similarly, the term ‘TALK’ can be

taken to correspond with the term ‘TALK/SEND’ on the SA model.

The procedures for mounting a PM on a wall and changing the standard gooseneck

mic for a shorter one are also described.

In addition to the installation aspects, a User Section includes a simplied

description of the PM’s operation; it is recommended that installers should

photocopy this section (or download a PDF copy of this manual from the Cloud

website and print the section off), and leave a copy for the operator.

SPOT ANNOUNCER (SA) MODELS

PM Models PM4-SA and PM8-SA have identical paging microphone functions to the

PM4 and PM8, but also include Spot Announcer capability. Up to four (PM4-SA) or

eight (PM8-SA) pre-recorded messages can be stored internally on a standard SD

memory card. As well as the messages, up to four (PM4-SA) or eight (PM8-SA) pre-

announcement chimes can be stored on the same card. An SD card is supplied with

each PM-SA unit, containing pre-recorded sample chime les.

The SD card is plugged into a dedicated card slot, accessed through the baseplate of

the unit.

A selection of commonly-used, pre-recorded messages is available to download from

www.cloud.co.uk.

PM4/8/12/16 & PM4/8-SA Installation and User Guide v1.2

Memory cards

SA models of the PM accept standard SD cards with a capacity of up to 2 GB or

SDHC cards up to 32 GB. MiniSD/MiniSDHC or MicroSD/MicroSDHC cards can also

be used with the appropriate adapter, up to the same maximum capacities.

To access the memory card slot, rst disconnect the PM from its power supply

source (if necessary) according to the powering method - by unplugging the external

PSU, the Digital Paging Interface CAN OUT connector, or by turning off the host

mixer. Invert the unit and undo the two pan-head hex-socket screws securing the

card slot cover with a 2 mm hex key.

Not to scale

SD card

Insert the card oriented as shown (pins away from you), and slide into the card

holder as far as it will go.

Sound les - types

The PM-SA is able to play sound les recorded in either MP3 or WMA (Windows

Media Audio) format, of the following types:

• MP3 les - MPEG 1/2/2.5 layer2/3 decoding, data rate 32 kbps ~ 320 kbps,

including VBR

• WMA les - WMA format, data rate 32 kbps ~ 384 kbps

• Sampling frequencies supported: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz,

24 kHz, 32 kHz, 44.1 kHz or 48 kHz

Announcement and chime sound les should be prepared on a computer (with an

SD card slot), and then saved to the card with the lenames given in the following

section. Files may be of any duration, but please see the section “Message/chime

duration and message cancellation” on page 42. Note that the write-protection tab

must be in the ‘unlocked’ position when les are being copied to the card. Set the tab

to ‘lock’ before inserting the card in the PM’s card slot.

Filenames

SA models of the PM will recognise les of the above types with the following

lenames:

Message les: M_x.mp3 or M_x.wma

Chime les: C_x.mp3 or C_x.wma

In both the message and chime lenames, x must have a value between 1 and 8. Thus

valid message lenames are M_1.mp3 to M_8.mp3, and valid chime lenames are

C_1.mp3 to C_8.mp3 (or their *.wma equivalents). All other les on the memory

card will be ignored.

The sound le M_1.mp3 (or M_1.wma) will be played when MESSAGE button 1

is pressed; the remaining sound les correspond numerically to the other buttons in

exactly the same way.

The sound le C_1.mp3 (or C_1.wma) is always used as the pre-announcement

page chime. Pre-recorded messages may be preceded by either C_1.mp3 or

C_2.mp3 (or their *.wma equivalents). Additionally, any chime le may be assigned

to a zone group to precede a pre-recorded message. See “Chime settings – SA

models only” on page 41 for details of how to congure chime settings, and

“Assigning a chime to a zone group (SA models only)” on page 36 for details of

chime assignment to zone groups.

Filenames M_5.mp3 to M_8.mp3 and C_5.mp3 to C_8.mp3 (or their *.wma

equivalents) will be ignored by a PM4-SA.

Note that all chime and message les must be saved in the memory card’s root directory.

The PM-SA cannot play sound les located within folders.

USING THE PM (NON-SA MODELS) -

USER INSTRUCTIONS

To the installer: please photocopy pages 14 & 15 and leave with the customer.

General Dos and Don’ts

When making an announcement:

• Think what you need to say before making the announcement.

• Speak slowly and clearly in a normal speaking voice.

• Don’t “swallow” the microphone; unless you are in a particularly noisy

environment your mouth need be no closer than 4 - 5 inches (10 – 12 cm) from

the mic.

• Don’t start speaking before you press the TALK button, and then wait until the

pre-announcement chime (if active) has sounded in full before starting.

• Don’t release the TALK button until the announcement is nished.

• Don’t twist the gooseneck into odd shapes – it isn’t a toy!

Paging one or more zones

1. Press the ZONE button(s) for the zone(s) to which the announcement is to

be made; the LEDs corresponding to the selection will illuminate. (An incorrect

selection may be cancelled with the CLEAR button.)

2. To start announcing, press and hold down the TALK button (the BUSY LED

illuminates).

3. Make the announcement.

4. Zones may be selected/deselected while the TALK button is pressed.

5. When the announcement is nished, release the TALK button.

NOTE: Once the talk button is released, the zone selection may either automatically

clear or remain set for further announcements, depending on how the unit was

congured at installation. If it remains set, it may be cleared by pressing the CLEAR

button.

PM4/8/12/16 & PM4/8-SA Installation and User Guide v1.2

15

Paging all zones

1. Press and hold the CALL ALL button; all the LEDs for enabled zones and the

BUSY LED will illuminate.

2. Make the announcement.

3. Zones may be selected/deselected during the announcement.

4. When the announcement is nished, release the CALL ALL button.

Paging a Zone Group

1. Press the GROUP button for the required zone group. (The zone LEDs

corresponding to the zones dened for the group will illuminate.)

2. Press and hold down the TALK button.

3. Make the announcement.

4. Zones may be added/removed during the announcement. (NOTE - this is only

“per-announcement”; it does not alter the group denition).

5. Release the TALK button.

Announcement Interruption (Multiple PM

systems only)

If the system has more than one PM microphone, it is possible that announcements

may be attempted from different microphones simultaneously. Priority assignments

made during the system installation can prevent two microphones on the network

from making an announcement at the same time. You may therefore nd that your

announcement is temporarily overridden by another announcement, from a PM with

higher priority.

If your announcement conicts with one from a higher priority microphone, yours will

be cut off and the interrupting announcement will take over. The interrupted PM will

indicate this condition by the ZONE LEDs ashing. The selection LEDs will remain lit

so that you can make your announcement again once the system is free.

INSTALLATION

Accessing the internal PCB

With most installations, it will be necessary at some point to access the PM’s internal

PCB. Access is required to make connections to the analogue interface (possibly including

DC power connections) and to connect the associated audio output, to move the

various conguration jumpers, to adjust the mic or chime levels and, on the SA models, to

connect to the external message trigger inputs, if used.

The standard (non-SA) and SA models of the PM are tted with different PCBs, but the

housing and method of access are the same. Refer to “PCB layout diagrams” on page 52

for PCB layout diagrams showing locations of jumpers, pre-set controls, connectors and

other primary PCB items.

To gain access to the PCB, rst disconnect any source of external power (e.g., a local

external PSU or the Digital Paging Interface). Then remove the ve pozidrive screws

securing the bottom cover plate onto the moulded housing. Gently lift the housing free,

noting that the PCB to which the top panel components are mounted is connected to

the lower PCB by a ribbon cable. Take care not to stretch or snag either this or the cable

from the gooseneck mic. The ribbon cable may be unplugged from the PCB to give easier

access to the board, if wished.

Re-assembly is the reverse procedure; always use the same screws.

Mounting Options

In most cases, the PM will be used as a desk-top, free-standing unit. In situations

where desk space is at a premium, or where access to the microphone needs to be

restricted, an alternative mounting method is to x it on a vertical surface such as a

wall. In this case, it may be appropriate to t a shorter gooseneck mic, as the standard

one (300 mm) may prove awkward in use and possibly constitute a hazard.

Free-standing

No special provisions are needed to use the PM in a free-standing mode. Cable access

is via the rear glands and the unit is provided with four rubber feet to prevent slipping

on a polished surface. The standard 300 mm gooseneck microphone will be suitable

for all normal desk or counter locations.
